Zac Efron EARMUFF STUD

Zac Efron braved some of the coldest temperatures in NYC in years to continue work on his new film ‘Are We Officially Dating?’ The actor kept warm with ear muffs as he made his way into a cafe for a scene, where he sipped warm coffee as icicles appeared to form on the window. The temperature was said to have dropped to 11¡F, the lowest since 2011. Photos: PacificCoastNews.
